When do I go back to the doctor?!

Okay so two weeks ago I had the WORST sore throat of my life. I went to the doctor, they checked for strep and it was negative. After two days the sore throat went away, but my ears felt clogged. After that it turned into a cough and congested nose.( TMI time) then I began blowing out and coughing up green and yellow mucus. All while my body felt totally fine, no fever. Since then every morning I have to blow my nose and it’s green or yellow, and then my nose would bleed. Assuming from all the blowing and being dry. It doesn’t bleed every day. Now this only happens in the morning. I have to blow my nose and my ears feel clogged. Yesterday was two weeks. Why is this taking so long to leave my body? I just don’t have the extra 40$ for a copay right now. Anyone have any ideas on what this is and if I need to go back or just wait it out??
